This error is indicating that there is an issue with the syntax in your code. Specifically, it is saying that there is an unexpected symbol before the "||" token.

To fix this error, you need to look at the code around where the error is occurring and check for any syntax errors. It is possible that you are missing a closing parenthesis or a semicolon, or that you have an extra symbol that is causing the issue.

Once you have identified the syntax error, fix it and try compiling your code again. If you still encounter errors, repeat the process until all errors have been resolved.
